J. Bert Johnson's professional staff empowers patients with sets of shimmering chompers. After doctors examine teeth for gum disease, oral cancer, and tiny reclusive ghosts, dental specialists take panoramic x-rays and scrub sullied fangs. Alternatively, clients who opt for whitewashed maws receive a set of Ultradent whitening trays and Opalescence PF 15%, a bleaching gel with carbamide peroxide and potassium nitrate fluoride to decrease sensitivity. During the initial 30-minute appointment, doctors craft custom trays by taking impressions of patients' teeth with the help of a skilled character actor. For two weeks, patients don their trays nightly, resulting in a whitened shine that can manifest within four days and last up to five years.
